Embodiment 1

[0018] see Figure 1-2 , in the embodiment of the present invention, a copper ore abandoned land soil heavy metal pollution remediation device includes a body 5, the upper and lower parts of the body 5 are respectively provided with an upper chamber 26 and a lower chamber 28, and the upper chamber 26 and the lower chamber 28 are respectively equipped with a conveying and breaking up assembly and a stirring electrolysis assembly, and the conveying and breaking up assembly and the stirring electrolysis assembly are driven by a drive mechanism installed on the body 5, and the upper chamber 26 is also driven by a U-shaped The conveying pipe 12 communicates with the lower chamber 28, and is used for conveying mud through the U-shaped conveying pipe 12. The body 5 is also equipped with an infusion device and an exposure device for replenishing liquid and conveying compressed air to the middle of the upper chamber 26. gas device.

[0019] In the embodiment of the present invention, ...

Embodiment 2

[0021] see Figure 1-4 , the difference between this embodiment and embodiment 1 is:

[0022] In this example, if figure 2 As shown, the upper chamber 26 is a horizontally arranged cylindrical structure, and the conveying and breaking assembly includes a rotating tube 22, a first screw blade 23, a breaking rod 24 and a second screw blade 27, and the rotating tube 22 Axially installed in the middle part of the upper chamber 26, and the two ends of the rotating tube 22 are in sealing and rotating connection with the body 5, and some breaking rods 24 are installed on the rotating tube 22 in the middle part of the upper chamber 26. The first helical blade 23 and the second helical blade 27 for conveying the soil to the right are respectively installed on the rotating pipe 22 on the side, and the first helical blade 23 and the second helical blade 27 have a better squeezing and conveying effect on the soil , Breaking up the rod 24 has a better effect of breaking up the soil.

Abstract

The invention relates to the field of soil remediation. The invention relates to a copper mine wasteland soil heavy metal pollution remediation device. The device comprises a machine body, an upper cavity and a lower cavity are formed in the upper portion and the lower portion of the machine body correspondingly, a conveying and scattering assembly and a stirring and electrolyzing assembly are respectively mounted in the upper chamber and the lower chamber, the conveying and scattering assembly and the stirring and electrolyzing assembly are driven to work through a driving mechanism installedon the machine body, the upper chamber is further communicated with the lower chamber through a U-shaped conveying pipe, and the machine body is further provided with a liquid conveying device used for supplementing liquid to the middle of the upper chamber and an aerating device used for conveying compressed air to the middle of the upper chamber. The device is novel in structure and good in copper mine waste land soil heavy metal removal effect, and the purpose of well repairing soil can be achieved.

Description

technical field [0001] The invention relates to the field of soil remediation, in particular to a device for remediating soil heavy metal pollution in abandoned copper mines. Background technique [0002] Soil heavy metal pollution refers to human activities, the content of trace metal elements in the soil exceeds the background value, and the excessive content caused by excessive deposition is collectively referred to as soil heavy metal pollution. Soil heavy metals refer to the phenomenon that human activities add metals to the soil, resulting in the heavy metals in the soil being significantly higher than the original content, and causing the deterioration of the quality of the ecological environment. [0003] Mining has been one of the important activities of social and economic development since ancient times. It not only provides a variety of valuable raw materials for economic construction, such as non-ferrous metals, minerals, etc., but the mining process inevitably ...
